Hello,
I have an 02 1500 3.7, has 160,000 miles on it. Recently the truck started stalling and check light came on, code was for a small evap leak I found and fixed the leak no more light but continues to stall. I replaced three vaccum hoses, the IAC and the upstream O2 sensor and no luck. The comp. isn't pulling anymore codes. If I brake in gear (5 speed) the truck slows normally however, as soon as I engage the clutch and take it out of gear the truck rapidly loses RPM's and dies. Any suggestions?

 

Try resetting the PCM by disconnecting the battery.
If it still stalls try grounding the throttle body.

 

I tried resetting the PCM after the replacement of the IAC and the O2 sensor no luck. I forgot to mention that I thoroughly cleaned the throttle body, had it smoke tested for vac. leaks. I am not sure what you mean by grounding the throttle body???

Thanks for your reply!

 

I assume your TB is metal, if so...take at least 10 gage wire and run it from one of the TB bolts to the battery ground.
Wal Mart has a 49" mower battery cable that is perfect for this @ $6 .
Al ot of guys on here have done this and it's smoothed out rough idling,cured stalling issues and improved throttle response.
Try it....it can't hurt.

 

I will give this a shot and post the results! Thank you!
